無(wú)介質(zhì)或輸送介質(zhì)流量小：使轉子主軸與穩定軸承干摩，燒碎軸承。磁力泵是由輸送介質(zhì)給滑動(dòng)軸承提供潤滑和冷卻的，在沒(méi)有開(kāi)入口閥或出口閥的情況下，滑動(dòng)軸承因無(wú)輸送介質(zhì)潤滑和冷卻而導致高溫從而損壞。
隔離套損壞：磁力泵的磁力聯(lián)軸器是由泵所輸送介質(zhì)冷卻的，如果介質(zhì)中有硬質(zhì)顆粒，很容易造成隔離套劃傷或劃穿，有時(shí)如果維護方法不當也有可能造成隔離套的損壞。
磁力泵因氣蝕而導致的問(wèn)題：泵產(chǎn)生氣蝕的原因主要有泵入口管阻大、輸送介質(zhì)氣相較多、灌泵不充分、泵入口能頭不夠等原因。氣蝕對泵的危害大，發(fā)生氣蝕時(shí)泵劇烈振動(dòng)，平衡嚴重破壞，將導致泵軸承、轉子或葉輪損壞。這是磁力泵故障發(fā)生的常見(jiàn)原因(圖\文www.lfsvw.com/)。

No media or transmission medium flow so that the rotor spindle and bearings: stable dry friction, burning up the bearing. Magnetic pump is determined by the conveying medium for sliding bearing for lubrication and cooling, in the absence of open entrance valve or outlet valve, sliding bearing for lubrication and cooling conveying medium to high temperature and damage.
The isolation sleeve damage: magnetic pump magnetic coupling is pumped by the transmission medium cooling, if in the medium of hard particles, is very easy to cause the isolation sleeve scratch or cut through, sometimes if maintenance methods also have the potential to cause the isolation sleeve damage.
Magnetic pump due to cavitation which leads to the question: pump cavitation main pump entrance pipe resistance big, medium gas phase more, irrigation pump, pump entrance can not fully head is insufficient wait for a reason. The pump cavitation damage, cavitation occurs when the pump vibration, balance seriously damaged, will cause the pump bearing, rotor or impeller damage. This is a common cause of magnetic pump fault.
